Earth’s core 1,000 degrees hotter than expected

Earth’s internal engine is running about 1,000 degrees Celsius (about 1,800 degrees Fahrenheit) hotter than previously measured, providing a better explanation for how the planet generates a magnetic field, a new study has found.

A team of scientists has measured the melting point of iron at high precision in a laboratory, and then drew from that result to calculate the temperature at the boundary of Earth’s inner and outer core – now estimated at 6,000 C (about 10,800 F). That’s as hot as the surface of the sun.

Maybe it is just getting hotter internally?
